复杂条件下山区高路堤弹塑性固结问题的有限元分析

针对山区高路堤的基本特点,利用有限元法分析了不同地形地貌、接触条件、地下水出露位置和排水条件、填筑速度下山区高路堤的弹塑性固结问题,得出山区高路堤变形与破坏问题的规律。利用此规律可以较为全面地认识山区高路堤的变形与破坏形态,并可有效地指导实际施工。

FINITE ELEMENT ANALYSIS ON ELASTO-PLASTIC CONSOLIDATION OF HIGH EMBANKMENT IN MOUNTAINOUS AREA UNDER COMPLEX CONDITIONS

Based on the main features of high embankment in mountainous area,finite element analysis is made on the elasto-plastic consolidation under complex conditions with the consideration of different land forms,different contact conditions,different outlet locations and drainage conditions of groundwater,and different filling speeds. The relations between failure and deformation of high embankment are therefore obtained. The results are helpful to understand the failure and deformation of high embankment,and can provide reference to construction.
